Abstract
A lamp has a carrier device and at least one lighting device mounted on the carrier device. The at least one lighting device has a carrier part, a plurality of lighting units which are arranged on a lateral wall of the carrier part, and a reflector device fastened to the carrier part. The reflector device has at least two reflector portions at a distance from one another in a longitudinal direction, which are each formed by reflector surfaces which are concavely curved in at least two curvature directions, wherein the at least two reflector portions are oriented facing the lateral wall of the carrier part, and wherein in each case one lighting unit is assigned in each case to one of the at least two reflector portions.
Claims19
A lamp, comprising:
- a carrier device;
- and
- at least one lighting device extending in a longitudinal direction and mounted on the carrier device, the lighting device comprising:
- a carrier part that includes a lateral wall extending in the longitudinal direction and having a first surface and a second surface oriented opposite to the first surface, a first end wall extending transverse from a first end of the lateral wall in a transverse direction, and a second end wall extending transverse from a second end of the lateral wall parallel to the first end wall,
- a plurality of lighting units which are arranged on the first surface of the lateral wall of the carrier part, and
- a reflector device fastened to the carrier part and extending between the first and second end walls;
- wherein the reflector device includes at least two reflectors formed by reflector surfaces which are concavely curved at least with respect to the longitudinal direction and with respect to a vertical direction so as to form a bowl-shaped or spoon-shaped cavity,
- wherein the vertical direction extends transverse to the longitudinal direction and to the transverse direction;
- wherein the at least two reflectors are separated from each other in the longitudinal direction by a planar intermediate segment extending in the longitudinal direction parallel to the first surface of the lateral wall of the carrier part;
- wherein the at least two reflectors are oriented facing the first surface of the lateral wall of the carrier part;
- and
- wherein a lighting unit is assigned in each case to one of the at least two reflectors.

A lamp comprising:
- a carrier device;
- and
- at least one lighting device mounted on the carrier device, the lighting device comprising:
- a carrier part which includes a lateral wall extending in a longitudinal direction and having a first surface and a second surface oriented opposed to the first surface, a first end wall extending transverse from a first end of the lateral wall in a transverse direction, and a second end wall extending transverse from a second end of the lateral wall parallel to the first end wall,
- a plurality of lighting units which are arranged on the first surface of the lateral wall of the carrier part,
- a plurality of cooling stacks placed one behind the other with respect to the longitudinal direction,
- wherein the cooling stacks are formed on the second surface of the lateral wall of the carrier part by peripheral walls extending in a vertical direction and forming channels having a completely closed cross section, the vertical direction extending transverse to the longitudinal direction and to the transverse direction,
- wherein the peripheral walls connect two openings of the channel that are arranged opposite one another in the vertical direction, and
- a reflector device fastened to the carrier part and extending between the first and second end walls,
- wherein the reflector device includes at least two reflectors that are positioned distanced from one another in the longitudinal direction, each of the at least two reflectors being formed by reflector surfaces which are concavely curved at least with respect to the longitudinal direction and with respect to the vertical direction so as to form a bowl-shaped or spoon-shaped cavity,
- wherein the at least two reflectors are oriented facing the inner surface of the lateral wall of the carrier part, and
- wherein a lighting unit is assigned in each case to one of the at least two reflectors.
